I also couldn't live with the guilt of choosing my own life and my child dying in vain. My children are teens and we're very close. They are very mature, lucid, rational, for teens anyway. Having a heart to heart with them would be paramount. I'm all they got. And they're not self-sufficient. So if I went out for one then two youngsters are on their own. Where as if one of them went, I'm still around to care for the other! I wouldn't "make" them choose but I would try to reach an understanding and agreement of what's in our family's best interest. I'm sure there's things I couldn't do to save my kids life. But I'd do most anything to preserve their life. Giving up my heart for one of them- yeah I'd do it.
